Table 3. Receiver operating characteristic curves of the indexes under evaluation as predictive markers of anastomotic leakage.

Marker	AUC	95% CI	P value	Cutoff	Sensitivity
Diet	0.456	(0.317, 0.595)	ns
N	0.737	(0.639, 0.835)	0.000	4.105	0.72
D1–3 P-L	0.643	(0.536, 0.75)	0.021	220.14	0.88
D4–7 N-L	0.628	(0.505, 0.752)	0.038	9.496	0.6

AUC, area under the curve; ns, not significant; N, neutrophil; D1–3, postoperative days 1–3; D4–7, postoperative days 4–7; P-L, platelet-to-lymphocyte; N-L, neutrophil-to-lymphocyte.
